Jim Grosbach 1755b3964f For ARM stack frames that utilize variable sized objects and have either ... large local stack areas or require dynamic stack realignment, allocate a base register via which to access the local frame. This allows efficient access to frame indices not accessible via the FP (either due to being out of range or due to dynamic realignment) or the SP (due to variable sized object allocation). In particular, this greatly improves efficiency of access to spill slots in Thumb functions which contain VLAs. rdar://7352504 rdar://8374540 rdar://8355680 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112883 91177308-0d34-0410-b5e6-96231b3b80d8		2010-09-02 22:29:01 +00:00
